Question

Q.1 Four years before, age of mother was three times the age of her daughter . Write a linear equation to represent this situation and draw a graph.
Q.2 The taxi fare in a city is as follow -
for the first km. the fare is Rs 8 and for the subsegent distance is Rs 5 per kilometer. Taking the distance carried as x km and total fare as Rs y , write a linear equation for this information and draw its graph.

Answer 1

Q1:linear eq: let the mother's age be x and daughters age be y so
x-4=3(y-4)
= x-3y=0
Q2:linear equation: distance=x
Total fare=y
Hence acc. to the question=(5(x-1))+8=y
5x-y+3=0
